Support disabling unit tests

[tsturge]

Support config: disabled for unit tests. (#9109)

Also, when a model is disabled, disable the corresponding unit tests automatically. (#10540)

Problem

config:
enabled: false

Solution

Check for the config: enabled variable while parsing the unit test. If it is set to false, mark the unit test as disabled.

I like this. Especially because the unit tests are now broken when we have ctx like vars inside the model. The way I was handling this was by commenting them out.

Hi! I was eagerly waiting for this to be released. I saw that this PR was merged 3 weeks ago. A new dbt-core version (1.8.9) was released one week ago but this feature doesn't seem to work there yet. This unit test:

version: 2

unit_tests:
  - name: consolidate_gmv_currencies
    config: 
      enabled: false 
    model: validate_consolidate_gmv_currencies

gets still listed by dbt list

Am I missing something? Thanks

@maxmarcon the changes in this PR weren't included in 1.8.9, but they are included in 1.9.0. I've tested out disabling them as you have above, and it's working for me.

While explicitly disabling a unit test using the below code is working:

version: 2

unit_tests:
  - name: consolidate_gmv_currencies
    config: 
      enabled: false 
    model: validate_consolidate_gmv_currencies

I'm still getting parsing errors when a model is disabled and a unit test is not explicitly disabled:

Parsing Error
  Unable to find model 'disabled_model' for unit test 'unit_test_for_disabled_model' in ...

Whether I have the model disabled using conditional logic such as config(enabled=var('model_enabled', false) != false) or config(enabled = false) doesn't make a difference.

It seems like the unit test should be disabled in this situation based on the changes made in core/dbt/parser/unit_tests.py in this PR. It looks like the unit tests added in this PR are testing for when unit tests are disabled and not when models are disabled, but I could be wrong about that.

I'm testing this out on dbt-core v1.9.0 and dbt-bigquery v1.9.0. Please let me know if I'm doing something wrong - thanks!
